ALBERT E. HOLADAY, 0F NAUGATUCK, CONNECTICUT, ASSIGNOR TO THE AMERICAN WRINGER COMPANY, OF WOONSOCKET, RHODE ISLAND, A CORPORATION OF RHODE ISLAND.

PRESSURE-ROLL RELEASE FOR WRINGERS.

Specification of Letters Patent.

Patented Nov. 14, 1916.

To all whom it may concern:

Be it known that I, ALBERT E. HOLADAY, a citizen of the United States, residing at Naugatuck, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Pressure- Roll Releases for Wringers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in pressure roll release for wringers, the object being to provide a pressure roll release which is exceedingly simple and cheap in construction and is in the nature of an improvement upon my applications Serial Nos. 88,009 and 88,010.

Another object of my invention is to provide a pressure roll release in which the top bar of the wringer frame is held in position by a spring formed of a single piece of wire having depending ends cooperating with hooks carried by the frame of the wringer in such a manner that the top bar will be held rigidly when the wringer is in use, and in such a manner, that by exerting a downward pressure upon the spring, the same will be elongated so as to throw the ends from off of the hooks so as to release the top bar and through the medium of the pressure bar, the upper pressure roll will be released instantaneously.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawing Figure 1, is a side elevation of a wringer partly in section, showing the application of my improved construction of pressure release thereto; and Fig. 2, is a top plan view of the same.

Like numerals of reference refer to like parts in the several figures of the drawing.

In carrying out my invention, I employ a wringer frame 1 formed of slotted side bars 2 connected together adjacent their lower ends by bars 3 and at their upper ends by a top bar 4 which fits within the slotted upper ends of the side bars 2, as clearly shown in Fig. 1, said bar having threaded bearings 5 in which are mounted pressure screws 6 adapted to engage bearing plates 7 of a pressure bar 8 slidably mounted within the slots of the side bar and provided with a pressure spring 9, the ends of which bear upon a bar 10 which is mounted upon the upper faces of bearing blocks 11 in which is mounted the shaft 12 of the upper pressure roll 13.

Arranged below the bearing blocks 11 are bearing blocks, not shown, in which is mounted the shaft 14 of a lower pressure roll 15. The shafts 12 and 14 are preferably provided with gears, not shown, to each side of the pressure rolls which are incased by gear; casings 16 carried by the bar 10.

Mounted on the top bar 4 is a bowed spring 17 which is provided with depending end portions 18 adapted to engage hook members 19 carried by U-shaped members 20 arranged over the upper ends of the side bars 2 so as to hold the top bar 4 in the position shown in Fig. 1. The bowed spring 17 is preferably formed of a single piece of wire bent to the desired shape, having its ends connected together by a connecting member 20 forming the plate which is adapted to be struck by the operator so as to elongate the spring, whereby the depending ends 18 will be moved from under the hooks 19 to release the top bar 4 which in turn will release the pressure on the pressure bar 8 and allow the upper roll 13 to move upwardly so that if an operators hand should accidentally be caught between the pressure rolls, the pressure thereon will be instantly released.

In order to facilitate the movement of the bowed spring when pressure is brought to bear thereon, the end of the bar 4 is provided with bearing plates 21 upon which the horizontal portions 22 of the bowed spring 17 normally rest so as to prevent upward movement of the top bar. The pressure screws 6 extend between the spaced bars of the spring 17 so as to allow the same to be readily manipulated.

From the foregoing description, it will be seen that I have-provided a pressure release for wringers which can be readily incorporated in the ordinary wringer construction so as to instantly release the pressure on the pressure rolls by simply exerting a downward pressure upon the bowed spring holding the top bar in position within the wringer frame.

I claim:

1. A. clothes wringer, comprising a frame having pressure rolls and pressure means therefor, a top bar carrying-pressure screws cooperating with said pressure means, hooks carried by the side bars of said frame, and a bowed spring having depending end portions cooperating with said hooks for normally holding said top bar within said frame. 1

2. A clothes wringer, comprising a frame having pressure rolls mounted therein, pressure means for said rolls,-a removable top barmounted in said frame, pressure screws mounted in said top bar cooperating with said pressure means, bearing plates mounted upon said top bar, a bowed spring having depending end portions carried by said top bar, and hooks extending outwardly from the ends of said side bars adapted to be engaged by the depending ends of said spring for normally holding said top bar in. position within said frame.

3. A clothes wringer, comprising a frame having pressure rolls and pressure means therefor, a removably mounted top bar carrying pressure screws cooperating with said pressure means, members secured 'to the upper ends of the side bars of said frame, laterally projecting hooks formed on said members, a bowed spring having horizontal portions bearing upon said top bar and ter minating in depending portions cooperating with said hooks for detachably securing said top bar within said frame.

4:. A clothes wringer, comprising a frame having pressure rolls and pressure means therefor, a removable top bar mounted in said frame, pressure screws carried by said top bar cooperating with said pressure means, a bowed spring formed of a single piece of wire bent to form a loop at each end, a hook carried by each side bar adapted to be engaged by the loop of said spring, the ends of said wire being connected by a connecting member, and bearing plates mounted upon said top bar upon which said spring is mounted.

5. A clothes wringer, comprising a frame having pressure rolls and pressure means therefor, members carried by said frame having laterally projecting hooks, a top bar mounted in said frame, pressure screws car ried by said top bar cooperating with said pressure means, a spring formed of a single piece of wire having a central bowed portion provided with a plate, said spring terminating in depending loop portions cooperating'with said hooks for holding said top bar in position within said frame.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

ALBERT E. HOLADAY.
